Deflection of a mass held by a beam due to the earths rotation.

Invensense is calling this a single axis "gyroscope".

It is not.

------------------------------------------

It probably only works in the vertical axis so using three is out
of the question.

However these specifications are amazing.

500 degrees per second rotation is extraordinary!!!!!

Shock is 10,000 G's meaning it can be fired from a gun.
How about a guided cannon shell?

Sensitivity is 2 milli volt per degree per second. No question about
it!!!!!!!!!!! THIS IS AN ANGULAR ACCELEROMETER!!!!!!!!!!!!!!!!!!!!

A millivolts is 1/1000th of a volt. If max output is 3 volt the resolution
is one part in 1,500 !!!!! Extraordinary for something so cheap.

It is cheap enough to put in a toy.
